Low-Emission Vehicle Greenhouse Gas Program
In 2004, CARB approved the landmark Pavley regulation to require automakers to control greenhouse gas emissions from new passenger vehicles for the 2009 through 2016 model years. These were the first regulations in the nation to control greenhouse gas emissions from motor vehicles, one of the largest contributors to climate change emissions in the state. Upon adoption of subsequent federal greenhouse gas standards by the United States Environmental Protection Agency (U.S. EPA) that preserved the benefits of the Pavley regulations, the Pavley regulations were revised to accept compliance with the federal standards as compliance with California’s standards in the 2012 through 2016 model years. This is referred to as the “deemed to comply” option.
In 2012, CARB approved the LEV III greenhouse gas regulation, which requires further reductions in passenger greenhouse gas emissions for 2017 and subsequent vehicle model years.
